• Registering in the iOS developer program as a minor

  - by maxluzuriaga

  Hi there. Recently I started learning to develop Apps for iOS, and while the simulator is fine for starting out, I've gotten to the point that I really should be testing the Apps I write on an actual device. As I'm sure you are well aware, to do this you must be a member of the $99/year iOS developer program, which also allows you to publish on the App Store. I'm more than happy to pay the fee, but my problem is that I'm still a minor, and to join the developer program you must be over 18 in the U.S. (I'm not sure how it works in other countries). I've talked to a few others that were in a similar position, but their responses have been varied. From what I've gathered, the best course of action is to register in the name of one of my parents. My problem with this is that if I were to ever publish an App on the store, it would be ideal to have my name as the seller instead of my Dad's. It wouldn't be the end of the world if this happened, but as I said, this wouldn't be ideal. Now I turn to you; is this a good plan? Have any of you been in this position or known somebody who has? Any other tips would be greatly appreciated. Thanks!

• ubuntu live cd start up error

  - by Emiel

  First off, I'm new to the Linux scene. This is my first attempt to make a single boot installation for Ubuntu. I tried it for a few days in dual boot with win7 and I was sold, so i removed the tumor my pc had to endure for so long (sorry laptop) and installed Ubuntu from an usb boot device. My dual boot was as follows: Windows 7 was installed on partition C from hdd1, the windows installer for Ubuntu installed Ubuntu on partition I on that same hdd, hdd1. In the live cd installation I did the normal execution for removing windows and it said that after the installation my partition would be 320gb big, that is the total size of my hdd, so I automatically assumed that it would format my whole hdd. Now the installation has completed and it tells me to restart my system, and here comes the problem: now I get a dashing white cursor on my screen after the BIOS load and it won't budge... it just stands there and it doesn't move on or load Ubuntu, the system gets very hot at this point... Then I tried to reinstall using the same live CD, it is still on my USB drive, but when I boot from the USB, I get the error: no such file with some address and the a grub rescue. What to do? I can get hold of a win7 copy, but I don't really want to use that crap again... Thanks for helping me out. Kind regards, Emiel

• How to reduce the CPU load on a hosting with WordPress installed as a CMS? [on hold]

  - by Akky Awesøme

  I have been using hostgators hatchling plan for three months. I got an email from the hosting that my website is creating an over load on CPU. They said that I am eating up their processor and as a precaution, they have temporarily suspended my account. When I contacted their customer support, they said: You have to optimize your database and use some sort of caching mechanism, where the script does not need to generate a new page with every request, helps to lower the over load that a script will cause. I am not a technical geek, I am wondering how I will do this thing. I don't have any resource to hire a web developer to do this job. My website is down for 48hours. I was using wp super cache along with cloudfare's free support. Now I have intalled optimize-db plugin and optimized my database. Please provide me with some more tips on how to optimize my database to reduce CPU usage. Any help would be appreciated.

• Life Is Full Of Changes (Part 1)

  - by Brian Jackett

  Today will be my last day with Sogeti.  I’ve been with Sogeti USA for just over 4 years.  In that time I’ve gotten to work on some great projects, develop relationships with some brilliant and passionate people, participate in the .Net developer and SharePoint communities, and grow my skills in a number of areas I’m passionate about.     As with all good things they must come to an end though.  I’ve accepted a position with another company and will provide more details once the transition has completed.  This decision was a difficult one to make but it provides a great career opportunity on many levels.  As much as my new schedule allows I plan to continue participating in local user groups, speaking at conferences, and blogging.     Speaking of which, you may have noticed my reduced blogging activity in the past few months.  In addition to a career change I’m also in the process of moving to a new residence (only a few miles from my current residence, so I’ll still be in Columbus.)  Searching for a new place, filling out paperwork, and all of the other work associated with this move has taken away a good chunk of the time I used to devote to blogging.  Once everything gets settled out with the move and job change I’ll re-evaluate how much time I can devote to blogging.     A big thanks to Sogeti and everyone who has been so supportive over my time with them.  It’s hard to move on, but I am excited for the prospects that the future will bring.         -Frog Out

• How to avoid jumping to a solution when under pressure? [closed]

  - by GlenPeterson

  When under a particularly strict programming deadline (like an hour), if I panic at all, my tendency is to jump into coding without a real plan and hope I figure it out as I go along. Given enough time, this can work, but in an interview it's been pretty unsuccessful, if not downright counter-productive. I'm not always comfortable sitting there thinking while the clock ticks away. Is there a checklist or are there techniques to recognize when you understand the problem well enough to start coding? Maybe don't touch the keyboard for the first 5-10 minutes of the problem? At what point do you give up and code a brute-force solution with the hope of reasoning out a better solution later? When is it most productive to think and design more vs. code some experiments to and figure out the design later? Here is a list of techniques for taking a math test and another for taking an oral exam. Is there is a similar list of techniques for handling a programming problem under pressure? ANSWERS: I think this is a valid answer: How To Solve It. I found the link as an answer to Steps to solve or approach towards a solution. There were also some really good tips at Is thinking out loud during an interview really the best strategy?. A great and concise argument for TDD is the first answer to TDD Writing code vs Figuring out the answer to a problem?. My question may be a near-duplicate of that one.

• How can I reduce the amount of time it takes to fully regression test an application ready for release?

  - by DrLazer

  An app I work on is being developed with a modified version of scrum. If you are not familiar with scrum, it's just an alternative approach to a more traditional watefall model, where a series of features are worked on for a set amount of time known as a sprint. The app is written in C# and makes use of WPF. We use Visual C# 2010 Express edition as an IDE. If we work on a sprint and add in a few new features, but do not plan to release until a further sprint is complete, then regression testing is not an issue as such. We just test the new features and give the app a good once over. However, if a release is planned that our customers can download - a full regression test is factored in. In the past this wasn't a big deal, it took 3 or 4 days and the devs simply fix up any bugs found in the regression phase, but now, as the app is getting larger and larger and incorporating more and more features, the regression is spanning out for weeks. I am interested in any methods that people know of or use that can decrease this time. At the moment the only ideas I have are to either start writing Unit Tests, which I have never fully tried out in a commercial environment, or to research the possibilty of any UI Automation API's or tools that would allow me to write a program to perform a series of batch tests. I know literally nothing about the possibilities of UI automation so any information would be valuable. I don't know that much about Unit testing either, how complicated can the tests be? Is it possible to get Unit tests to use the UI? Are there any other methods I should consider? Thanks for reading, and for any advice in advance.

• No MAU required on a T4

  - by jsavit

  Cryptic background One of the powerful features of the T-series servers is its hardware crypto acceleration, which dramatically speeds up the compute intensive algorithms needed to encrypt and decrypt data. Previously, administrators setting up logical domains on older T-series servers had to explicitly assign crypto resources (called "MAU" for historical reasons from the T1 chip that had "modular arithmetic units") to domains that had a significant crypto workload (say, an SSL based web server). This could be an administrative burden, as you had to choose which domains got the crypto units, and issue the appropriate ldm set-mau N mydomain commands. The T4 changes things The T4 is fast. Really fast. Its clock rate and out-of-order (OOO) execution that provides the single-thread performance that T-series machines previously did not have. If you have any preconceptions about T-series performance, or SPARC in general, based on the older servers (which, it must be said, were absolutely outstanding for multi-threaded applications), those assumptions are now obsolete. The T4 provides outstanding. performance for all kinds of workload, as illustrated at https://blogs.oracle.com/bestperf. While we all focused on this (did I mention the T4 is fast?), another feature of the T4 went largely unnoticed: The T4 servers have crypto acceleration "just built in" so administrators no longer have to assign crypto accelerator units to domains - it "just happens". This is way way better since you have crypto everywhere by default without having to manage it like a discrete and limited resource. It's a feature of the processor, like doing an integer add. With T4, there is no management necessary, you just have HW crypto everywhere all the time seamlessly. This change hasn't been widely advertised, and some administrators have wondered why there were unable to assign a MAU to a domain as they did with T2 and T3 machines. The answer is that there is no longer any separate MAU, so you don't have to take any action at all - just leave the default of 0. Summary Besides being much faster than its predecessors, the T4 also integrates hardware crypto acceleration so its seamlessly available to applications, whether domains are being used or not. Administrators no longer have to control how they are allocated - it "just happens"

• how to store and retrieve/generate UI?

  - by thindery

  I'm working on a site that will have hundreds, and eventually thousands, of paper products that users can customize online. Here is a very simple sample of what needs to be generated based on the product id: demo. This is a very simple version. I plan on replacing text fields with prettier elements(like the slider on tab 3). I imagine most of this can be achieved via jquery. So basically a product will have multiple pages(tabs), with multiple form elements on each page. I've never done a large scale project like this before and I am looking for ideas/suggestions for how I can store the info for each product that needs to be generated to create the UI. For each product, I need to store how many pages there are, what form fields are on each page, and the order of the fields on the page. As well as setting default text values and form options(font size, etc). Then with all this info stored somewhere, I can have the web app retrieve it and generate the UI with text fields, sliders, and other jquery-ish form enhancements, for that particular product. Can anyone toss out some suggestions, links, blogs, tutorials? I'm not really sure where to begin with this or what I need to start to investigate. I have experience with php, mysql, javascript, jquery, html, css, and that is really about it. I'm open to learning(and would enjoy exploring) new frameworks, programming, etc that will really get this web app working correctly, efficiently, and effectively. Maybe I should start looking into a mvc framework? like i said, i really have no idea what is the best approach. please let me know your suggestions!

• How much ethical is to accept second offer while serving notice period for first company? [closed]

  - by iammilind

  I had got an offer from a company X 2 months back. Though the compensation was pretty good, I asked for more. They declined and I continued my search for the best. I was expecting good companies (Y, Z) will contact me, but that din't happen. Then 2 months later, now I re-approached company X again and they issued me the same offer. I accepted it, resigned from my current company and serving the notice period (2 months). Now the twist: I got calls from Y and Z (good companies). They definitely give better compensation. If they select me then my plan is to accept the better offer from Y/Z and inform the X immediately that I have got better opportunity, so I will not be able to join the company... Is this ethical ? [Edit Note: I have to just send an acceptance email (i.e. no contract signing) which doesn't legally bind me to join that company. So, legally I am not doing anything wrong. However, I am worried that if I am doing right/wrong ethically.]

• Run Win7 Guest (raw disk) in Ubuntu (which was installed as Dual Boot on existing Win7)

  - by kingdango

  I installed Ubuntu 12.10 on top of Win 7 as a dual boot (awesome!). I'm hoping to use VirtualBox to run my original Win7 instance as a guest OS under Ubuntu. I found this existing question and followed the directions to no avail. I can get the VMDK file created but when I run it I just get a blank black screen with no additional information and Windows never loads. I see no HD activity or anything that would indicate it's loading. I used this command to create the VMDK file: VBoxManager internalcommands createrawvmdk -filename ~/.VirtualBox/Win7Native.vmdk -rawdisk /dev/sda3 It looks like everything was created correctly but I just get a blank screen when I run the VM. I do get this warning when I boot the VM: VirtualBox - Warning The virtual machine execution may run into and error condition as described below... The medium '/home/XXX/.VirtualBox/Win7Native.vmdk' has a logical size of 583GB but the file system the medium is located on can only handle up to 16GB in theory. We strongly recommend to put all your virtual disk images and the snapshot folder on a proper file system (e.g. etc3) with a sufficient size. ErrorId: Fat Partition Detected Severity: Warning How can I get this working?

• Quitting a small start-up where you are a primary developer?

  - by programmx10

  Just curious to hear from other people who may have been in similar situations. I work for a small startup (very small) where I am the main developer for a major part of the app they are building, the other dev they have does a different area of work than I do so couldn't take over my part. I've been with the company 5 months, or so, but I am looking at going to a more stable company soon because its just getting to be too much stress, overtime, pressure, etc for too little benefit and I miss working with other developers who can help out on a project. The guy is happy with my work and I think I've helped them get pretty far but I've realized I just don't like being this much "on the edge" as its hard to tell what the direction of the company is going to be since its so new. Also, even though I'm the main dev for the project, I would still only consider myself a mid-level dev and am selling myself as such for the new job search. Just to add more detail, I'm not a partner or anything in the company and this was never discussed, so I just work on a W2 (with no benefits of course). I work at home so that makes it easier to leave, I guess, but I don't want to just screw the guy over but also don't want to be tied in for too long. Obviously I would plan to give 2 weeks notice at least, but should I give more? How should I bring up the subject because I know its going to be a touchy thing to bring up. Any advice is appreciated UPDATE: Thanks everyone for posting on this, I have now just completed the process of accepting an offer with a larger company and quitting the startup. I have given 2 weeks notice and have offered to make myself available after that if needed, basically its a really small company at this point so it would only be 1 dev that I would have to deal with... anyways, it looks like it may work out well as far as me maintaining a good relationship with the founder for future work together, I made it out to be more of a personal / lifestyle issue than about their flaws / shortcomings which definitely seems to help in leaving on a good note

• What guidelines should be followed when implementing third-party tracking pixels?

  - by Strozykowski

  Background I work on a website that gets a fair amount of traffic, and as such, we have implemented different tracking pixels and techniques across the site for various specific reasons. Because there are many agencies who are sending traffic our way through email campaigns, print ads and SEM, we have agreements with a variety of different outside agencies for tracking these page hits. Consequently, we have tracking pixels which span the entire site, as well as some that are on specific pages only. We have worked to reduce the total number of pixels available on any one page, but occasionally the site is rendered close to unusable when one of these third-party tracking pixels fails to load. This is a huge difficulty on parts of the site where Javascript is needed for functionality built into the page, but is unable to initialize until a 404 is returned on the external tracking pixel. (Sometimes up to 30 seconds later) I have spent some time attempting to research how other firms deal with this sort of instability with third-party components, but have come up a bit short. The plan currently is to implement our own stop-gap method to deal with these external outages, but rather than reinventing the wheel, we wanted to find out how this is dealt with on other sites. Question Is there a good set of guidelines that should be followed when implementing third-party tracking pixels? I would love to see some white papers or other written documents about how other people have dealt with this issue.

• Users can benefit from Session Tracking

  I use to work for a large Dental Plan marketing website a few years ago and they had a large customer-driven website that sold Dental Plans to consumers. Their website started tracking users as soon as they hit their web servers, and then they logged everything they could about the user. There are a lot of benefits for using session tracking for both the user and the website. Users can benefit from session tracking due to the fact that a website can retain pertaining information for the user so that they do not have to re-enter the same information repeatedly. In addition, websites can hold specific items in a cart for each user so that they can pay for all of their  items at once when they are ready to complete their purchases. Websites can also benefit from session tracking because they can determine where a specific user came from and which advertising partner gave them a sale. This information is very useful when deciding on where to spend an advertising budget. There is only one real disadvantage when it comes to session tracking, Users can not really control what is actually tracked by a website. Yes, they can disable cookies and this will help, but that means that no tracking can be done at all. Most sites require users to have cookies enabled in order for users to make purchases or login to their accounts.

• South Florida Code Camp and Other Events

  - by MOSSLover

  My grandmother wanted me to make her a video when she heard I got MVP in SharePoint Server of one of my sessions.  I decided I haven’t visited in two years, so maybe I can do an in person session.  I googled around and found South Florida Code Camp, which will be Saturday, February 12th.  I will be doing a session at 9:50 in the morning on Silverlight just for my grandmother and whoever shows up.  Here is the link for more information: http://www.fladotnet.com/codecamp/. In the upcoming months I plan to return to SharePoint Saturday speaking.  We are also organizing another New York event on Saturday, July 30th.  We will open up submissions for sponsors and speakers somewhere after Best Practices Conference in LaJolla.  I will be speaking at Best Practices LaJolla and the The Expert’s Conference in the upcoming months.  I am really sorry for the lack of updates it’s just been incredibly crazy going back and forth to DC and not having internet on weekdays or having the slowest internet in the world has just not helped.  I am also trying to attend Coders 4 Charity this year, so I can visit some people in St. Louis.  I’ve already got an incredibly crazy schedule going for the year.  I might be helping organize more events.  I’m going to volunteer at New York Code Camp too doing whatever they need this year.  Check back for more updates.

• Search multiple tables

  - by gilden

  I have developed a web application that is used mainly for archiving all sorts of textual material (documents, references to articles, books, magazines etc.). There can be any given number of archive tables in my system, each with its own schema. The schema can be changed by a moderator through the application (imagine something similar to a really dumbed down version of phpMyAdmin). Users can search for anything from all of the tables. By using FULLTEXT indexes together with substring searching (fields which do not support FULLTEXT indexing) the script inserts the results of a search to a single table and by ordering these results by the similarity measure I can fairly easily return the paginated results. However, this approach has a few problems: substring searching can only count exact results the 50% rule applies to all tables separately and thus, mysql may not return important matches or too naively discards common words. is quite expensive in terms of query numbers and execution time (not an issue right now as there's not a lot of data yet in the tables). normalized data is not even searched for (I have different tables for categories, languages and file attatchments). My planned solution Create a single table having columns similar to id, table_id, row_id, data Every time a new row is created/modified/deleted in any of the data tables this central table also gets updated with the data column containing a concatenation of all the fields in a row. I could then create a single index for Sphinx and use it for doing searches instead. Are there any more efficient solutions or best practises how to approach this? Thanks.

• How do I create an efficient long, pannable, sprite-animated scene in a Windows Store game?

  - by Groo

  I am creating my first Windows Store application in XAML, and I cannot seem to find a proper example for the requirements I have. The basic idea of the app is to have a large scrollable canvas which would lazily start animating visible parts of the view as soon as user stops panning over a certain content (with some audio played also): My original idea was to use a StackPanel to add a bunch of custom controls, each of which would then animate itself once visible (with a short delay), but I have a couple of concerns: If the entire canvas is ~50 screen widths wide, is it feasible to load all content at the beginning, or do I need to plan doing some lazy loading during scrolling? For example, when I select a certain region in the Bing Travel app, it seems to lazily load tiles as I scroll it towards the end. Since content is stretched 100% vertically, and these animations are vectorized to be resolution independent, I am not sure if XAML (CompositionTarget) will be able to handle this, or I have to go for DirectX (MonoGame or C++) to get rid of flicker. Even better, is there an example for Windows 8 which uses a 100% vertically sized GridView with custom animated controls inside?

• Fast, accurate 2d collision

  - by Neophyte

  I'm working on a 2d topdown shooter, and now need to go beyond my basic rectangle bounding box collision system. I have large levels with many different sprites, all of which are different shapes and sizes. The textures for the sprites are all square png files with transparent backgrounds, so I also need a way to only have a collision when the player walks into the coloured part of the texture, and not the transparent background. I plan to handle collision as follows: Check if any sprites are in range of the player Do a rect bounding box collision test Do an accurate collision (Where I need help) I don't mind advanced techniques, as I want to get this right with all my requirements in mind, but I'm not sure how to approach this. What techniques or even libraries to try. I know that I will probably need to create and store some kind of shape that accurately represents each sprite minus the transparent background. I've read that per pixel is slow, so given my large levels and number of objects I don't think that would be suitable. I've also looked at Box2d, but haven't been able to find much documentation, or any examples of how to get it up and running with SFML.

• HTTP PHP Authentication and Android

  - by edc598

  I am working on a website for which I hope to have an application for as well. Because of this, I am creating PHP API's which will go into my Database and serve specific data based on the method/function called. I want to protect these API's from misuse however, and I plan on implementing Authentication Digest to do so. However one of the OS's I want to support is Android. And I know that a malicious user would be able to reverse engineer the Android app and figure out my authentication scheme. I am left wondering: 1. Is there a better way to protect these API's from misuse? 2. Is there a way to prevent a malicious user from reverse engineering the app and potentially seeing the source code for it, enabling them to see my authentication scheme? 3. If none of these are preventable, then is my only option to have a Username/Password cred specifically for the Android app, and when eventually hacked, change the creds and issue an update for the app? I apologize if this is not the place to post such a question. Still pretty new to StackOverflow. Thanks in advance for any insight, it would be quite helpful.

• Can I eventually consider myself a professional developer if I don't have a CS degree? [on hold]

  - by heltonbiker

  Question first, context later: If I am a dedicated, self-taught programmer, always seeking top-quality books AND READING THEM, while successfully applying all that new knowledge into my current work, could I call myself (and offer my work as) a PROFESSIONAL developer? How limiting (or how common) that is nowadays? I am afraid that, no matter how hard I study and practice, it could be too difficult to compete with "actual", college graduated developers, and potential employers might have doubts investing in an "undergraduated" person. Now, context: My former profession is from healthcare sector, then I studied mechanical engineering (quit in the middle), then I studied product design (master degree), and I ended up working (very happily) at an engineering company that manufactures medical devices. For more than two years now my main activity in this company is software development. The devices contain software, and we gave up hiring software development (domain knowledge needed, too much communication cost). My current company sees a lot of value in what I do, but I cannot afford the risk of depending on this single company for the rest of my life, you get it. But a lot of job offers require some minimal formal education, usually a CS degree. Fact is that I am sure this is my target profession, I don't plan to go to another area, it is a pleasure to dive into books that normal people would consider unreadable, but I'm 36 years old and can't see going back to college as a viable alternative.

• License compatibility question

  - by Ivaylo Slavov

  I have a question regarding software licenses. I plan to put a license to a framework that I have written. My intention is that the license should be open, in order to maintain a community. Also I want to control when a new version is released and which changes will be included. The license should allow the framework to be used with commercial products, therefore respecting their own license. I have done some quick research and I decided to double license my work under the Apache License 2.0 (ASL) and Eclipse Public License (EPL). My point is that the EPL will provide me the ability to control the release cycle as well as the contributions to the project and the Apache license will take care for any patents a 3rd party might want to use in a derived work. Also both are open licenses. My question is related to the GLP and LGPL licenses. If I have the above licenses to my framework, will it be possible and legal, for someone to create a derived work of my framework, that is also a derived work of, or links a library that is under the LGPL license? Thanks in advance. EDIT: To be clear I will explain how I expect things to work. The framework will define some common API for certain functionalities as well as a Wrapper class that will invoke an implementation of that API. The Wrapper will be part of the framework, but it will internally call the actual implementation. This implementation should be in a separate library, and such libraries I would like to be developed and maintained by community. Surely the community will have to access the framework but I want to limit changes to the framework by the community but I want to provide freedom for any API implementation (a derived work of the framework). The framework will enable flexible configuration mechanisms that will tell which implementation of an API will be used.

• Best way to setup hosts, subdomains, and IPs [closed]

  - by LynnOwens

  I own a domain, let's call it mydomain.com. I need to host the following off it: forums.mydomain.com www.mydomain.com blog.mydomain.com objects.mydomain.com I believe I can get 5 static IPs. I plan on assigning one each to those four hosts. Then I need to adhoc create names, all below objects.mydomain.com. For instance: one.objects.mydomain.com two.objects.mydomain.com three.objects.mydomain.com I need to create these names programatically, and without human intervention. Preferably, they would not get their own IPs. They would use the IP of objects.mydomain.com. First question: Does this mean that I need to host my own DNS? Second question: I'm using Apache as a web server. What does the virtual host configuration look like? I was experimenting with the following to understand how routing on domain names works and I always ended up at www. <VirtualHost *:80> ServerAdmin [email protected] ServerName www.mydomain.com ServerAlias www.mydomain.com DocumentRoot "E:/Static/www" RewriteEngine On RewriteRule ^(/www/.*) /www$1 </Virtualhost> <VirtualHost *:80> ServerAdmin [email protected] ServerName forums.mydomain.com ServerAlias forums.mydomain.com DocumentRoot "E:/Static/forums" RewriteEngine On RewriteRule ^(/forums/.*) /forums$1 </Virtualhost>
